Self-Organizing Hierarchical Particle Swarm Optimization of Correlation Filters for Object Recognition

IEEE Access, 2017
Advanced correlation filters are an effective tool for target detection within a particular class. Most correlation filters are derived from a complex filter equation leading to a closed form filter solution.

Parallelized Particle Filter With Efficient Pipelining on FPGA for Real-Time Ballistic Target Tracking

IEEE Access, 2023
In this paper, the problem of a real-time ballistic target tracking is addressed. Because the tracking process can be affected by the uncertainty in models and disturbances, probabilistic filters have been applied to solving the ballistic target tracking

Particle filters for partially-observed diffusions. [PDF]

, 2008
In this paper we introduce novel particle filters for a class of partially-observed continuous-time dynamic models where the signal is given by a multivariate diffusion process.

Tempered Particle Filtering [PDF]

Finance and Economics Discussion Series, 2016
The accuracy of particle filters for nonlinear state-space models crucially depends on the proposal distribution that mutates time t-1 particle values into time t values. In the widely-used bootstrap particle filter this distribution is generated by the state-transition equation.

Irrigation Amounts and Timing Retrieval through Data Assimilation of Surface Soil Moisture into the FAO-56 Approach in the South Mediterranean Region

Remote Sensing, 2021
Agricultural water use represents more than 70% of the world’s freshwater through irrigation water inputs that are poorly known at the field scale. Irrigation monitoring is thus an important issue for optimizing water use in particular with regards to ...

Numerical simulation of DPF filter for selected regimes with deposited soot particles

EPJ Web of Conferences, 2012
For the purpose of accumulation of particulate matter from Diesel engine exhaust gas, particle filters are used (referred to as DPF or FAP filters in the automotive industry). However, the cost of these filters is quite high.

Localisation of mobile nodes in wireless networks with correlated in time measurement noise. [PDF]

, 2011
Wireless sensor networks are an inherent part of decision making, object tracking and location awareness systems. This work is focused on simultaneous localisation of mobile nodes based on received signal strength indicators (RSSIs) with correlated in ...

An improved unbiased particle filter

Monte Carlo Methods and Applications, 2023
Abstract In this paper, we consider the filtering of partially observed multi-dimensional diffusion processes that are observed regularly at discrete times. We assume that, for numerical reasons, one has to time-discretize the diffusion process, which typically leads to filtering that is subject to discretization bias. The approach in [A.
